+
+ setup("my_test_name");
+ ok(run(app(["openssl", "version"])), "check for openssl presence");

+
+=head1 DESCRIPTION
+
+This module is a private extension of L<Test::More> for testing OpenSSL.
+In addition to the Test::More functions, it also provides functions that
+easily find the diverse programs within a OpenSSL build tree, as well as
+some other useful functions.
+
+This module I<depends> on the environment variables C<$TOP> or C<$SRCTOP>
+and C<$BLDTOP>. Without one of the combinations it refuses to work.
+See L</ENVIRONMENT> below.

+=begin comment
+
+One might wonder over the complexity of C<apps>, C<fuzz>, C<test>, ...
+with all the lazy evaluations and all that. The reason for this is that
+we want to make sure the directory in which those programs are found are
+correct at the time these commands are used. Consider the following code
+snippet:
+
+ my $cmd = app(["openssl", ...]);
- $saved_stderr = $opts{stderr} if defined($opts{stderr});
+ indir "foo", sub {
+ ok(run($cmd), "Testing foo")

- my $display_cmd = "$cmd$arg_str$stdin$stdout$stderr";
- $cmd .= "$arg_str$stdin$stdout 2> $errlog";
+If there wasn't this lazy evaluation, the directory where C<openssl> is
+found would be incorrect at the time C<run> is called, because it was
+calculated before we moved into the directory "foo".
